Enter SDF—our cavity-fighting, smile-saving superhero. Recently approved for use in the United States, this clear liquid can be painted on cavities
to prevent and eliminate decay. Learn what Silver diamine fluoride means for the future of kids’ cavities:

The SDF Timeline

SDF made its premiere in Japan 900 years ago and has been used overseas for over 30 years. It was first cleared in the U.S. for adults 21 and older as
a tooth desensitizer. But as SDF studies grew, researchers began to see how it could slow cavity growth.

Fillings are uncomfortable for kids. Between anesthesia and procedure, filling a cavity can take up to 30 minutes. And it only makes matters worse for
kids who are scared of the drill.

With SDF there’s no drill, no drugs and the deed is done in less than 5 minutes. This is especially helpful for kids with special needs.

What About the Cons?

The positives of SDF outweigh the negatives, according to the AAPD. One downside is it darkens the tooth decay, turning its brownish tint to black. However,
it doesn’t matter for baby teeth, as they’re going to fall out eventually. SDF is also cited for its unpleasant, metallic taste.

The Cost

Because it’s still relatively new, few insurance companies cover the cost. But it’s not all bad news. The out-of-pocket cost is much more affordable than
traditional fillings.
